Yokofutori : NAITOU ryu San-San Kaku senpou : part 1.

Shogi Opening traps : Yokofutori : NAITOU ryu San-San Kaku senpou : part 1.

(diagram 1)

1.P-7f P-3d
2.P-2f P-8d
3.P-2e P-8e
4.G-7h G-3b
5.P-2d Px2d
6.Rx2d P-8f
7.Px8f Rx8f
8.Rx3d B-3c
(diagram 1)







The diagram 1 is a typical starting of NAITOU ryu San-San Kaku senpou . In diagram 1 , you may think Sente can get material advantage by following moves ; 9.Rx3c+ Nx3c , 10.B*7g . After Gote's Rook escapes (for example 10...R-8b) , Sente will move 11.Bx3c+ Gx3c , 12 Bx3c+ (diagram 1') . Whether Sente can get an advantage or not ?

(diagram 1')




















(diagram 2)

After diagram 1
9.Rx3c+ Nx3c
10.B*7g Rx8h+
11.Sx8h R*2g
(diagram 2)


Gote doesn't escape his Rook , but exchanges it with Sente's 8h Bishop . And after the exchange , Gote can drop his Rook before Sente and gets a slight advantage .


Then in many cases , Sente players move 9.R-3f .
